It's not uncommon to know how to use things without understanding how they work. If we don't understand something, there is always a possibility that we might damage it.
Ezekiel in his vision first sees the face of a man. This is because 90% of the problems on earth are solved by God using human intelligence. Miracles are special interventions of God into man's situation.
Men were created for glory and honour. Glory means heavy weight, when you carry a heavy weight you will feel it. The bible says God can not share his glory with anyone but yet He is calling us for glory, how do you reconcile this?
